I made a couple of pages that allow the user to enter a pnumber and group number and see what material specifications match or on another page, select a material specification and see what the P Numbers, Group numbers and Type/Grades exist.

This information is not a replacement for a code book, just an example of a way to share infomation related to what we do.
